![]() ![]() The psychological space is inducted for stimuli to measure the distance between the stimuli so that the chances for generalization of a response being learned for one stimulus will be applied to any other invariant of the distance being measured between them. Shepard in 1987, explains that the response towards one object will be generalized to another object based on the distance between the two objects in the psychological space. The Universal Law of Generalization developed by Roger N. Experience and exposure to related things for a longer duration, also the current and immediately past stimuli could affect in determining similarity among objects. To construct stimuli and to state psychological outcomes, measures of hue, brightness, or pitch are used as they enter into far simpler relationships with behavior than the wavelength, intensity, and frequency. In addition to this, there are times when similarity is dependent on the behavioral responses to objects among a group of objects. It can be said that similarity is heavily based on the physical attributes of a stimulus. ![]() This is an important concept in cognition since it helps in object identification and categorization. Apart from this, other regions in the visual cortex deal with color perception and other factors. At this region, the depth of the object is processed, where a 2-D map of the object is formed to understand where objects are being placed in the space concerning us. Whatever is being perceived by the first area then moves on to the visual cortex area, called the primary visual cortex. The other one handles the motion and contrast of the object being perceived. One area deals with the color and the structure of the object. The light falling on the retina then moves on to the thalamus, where it moves into two areas. A smooth motion of the eye could result in motion blur. #Law of similarity psychology series#Eyes movies as a series of short jumps known as saccades. The next region is called the superior colliculus this is involved in regulating the motion of the eye. It means two presentations which are brought together in consciousness form a whole mental state, so that whenever a part occurs to consciousness it tends to revive the whole. Hamilton combines the Law of Contiguity and the Law of Similarity into one, viz., the Law of Red integration. The first region is called the pretectum, which helps in adjusting the size of the pupils based on the amount of light entering the eye. Thus the Law of Similarity involves the Law of Contiguity. Along-side, the optic nerve transmits information that is additional to two regions of the brain. There are electrochemical signals which move to the thalamus through the optic nerve, which then reaches the cerebral cortex. The point being that the better you understand these principles the more sucessful you can be at breaking them.It is in the cerebral cortex of the brain, visual perception takes place. Remember that these principles are not set in stone, and it is ok to break them. This is not to say that every composition needs to be perfectly balanced and symmetrical, there are many examples of artists who play with the idea of symmetry and balance and still are quite sucessful. While clearly balanced compositions will be more accesible. Some viewers who find a painting which is too difficult to read may spend less time trying to comprehend it. Notice how the figures aren't perfectly symmetrical on both sides of the work, however they are still balanced and neither side seems too "heavy".The larger idea at play here is that viewers want to "read" a painting in a systematic and organized manner. In Raphael's painting below we can see how by having a clear sense of symmetry adds to the structure of the entire composition. Symmetry and Order refers to the idea of how balance, and symmetry give the composition an overall feeling of solidity and structure. In general it is a good rule of thumb to think that warm colors will come forward in space while cool colors recede. Also notice how Matisse utilized contrast, as well as color to make the figures come to the front of the painting, and push the background back in space. It is also helpful to think of the ground as the negative space around the figures present. In the Matisse painting below we can see a clear differentiation between figure and ground. These differences can be furthered by utilizing a number of different techniques which can include contrast, color, intensity, and size. This is the idea that speaks to the human mind's tendency to separate figures from their backgrounds. ![]() The main points of Gestalt are summarized below the image. It is often used in both art as well as design to achieve the desired effect. These theories of painting come from a German form of psychology called Gestalt which simply states that the whole is greater than the sum of its parts. ![]()
